Faster than the speed of light...

Your light beam would travel at 2x speed of light ... same as when you throw something forward while travelling in a car. The objet has the speed of the car already and then also the extra one you gave it by throwing it.

...or it would travel back in time and knock you out before you attempt such a outrageous experiment.

The only thing faster than the speed of light is dark - because it has to get out of the way!

That's what I thought at the start, but now that I think about it, the light can still move at the speed of light without violating the conservation of momentum. Though if that's the case we might have photons that move at the standard c but have some other ridiculously unreasonable property, like a null or negative wavelength.

Or I could be totally wrong. Not that it matters much, this is sort of the reason moving faster than light is impossible in the first place...

Nothing!! will travel faster than the speed of light(locally). You can't "add up" the speed of light like with normal velocities. If you are moving at "c"(lightspeed) and you turn on lights they would move out no faster than c. If you shoot a bullet out front it would not move away from you faster than "c".
2 ships closing on each other at c would appear to be moving towards each other no faster than the speed of light. They would not be closing on each other at 2x light speed.

So no matter what you do things will ALWAYS move no faster than lightspeed, regardless of their velocity/position.

The only possible way is if they are spatially separated by great distances.
